I am 15 years old and building a robot. I would like to isolate each
circuit in my robot from the others so that if something goes wrong I'm
only going to lose one board not the lot.
For example if my motor controller goes haywire I don't won't to have
the possibility of losing my microcontroller board if a hi voltage
signal goes to one of its inputs etc etc.
Does anyone know of a chip I could put between digital signals going
from A to B and vise versa which would stop hivoltage signals etc going
I guess what I am saying is I want to blow up a cheap chip instead of
the more expensive chips.
Any hints, help would be great,
or if that fails try
